The accumulation of heavy metals in the soil not only causes serious damage to ecosystem, but also threatens human health through food chain. Exopolysaccharides have functions adsorbing and chelating reducing their bioavailability soil. In our study, exopolysaccharide-producing bacteria with a high efficiency cadmium (Cd) lead (Pb) were screened from metal-contaminated farmland. Through pot experiments, influence functional strains on size distribution, metal content, bacterial community structure aggregates lettuce was studied using high-throughput sequencing technology. results show that 11 secreting exopolysaccharides initially Among them, strain Z23 had removal rate 88.6% for Cd 93.2% Pb. at which removed by Z39 92.3%, Pb 94.4%. Both belong
